While Casio's G-Shock GB6900 was among the company's main focuses at CES 2013, there was yet another watch to be seen inside the company's booth. Interestingly enough, though, the Japanese firm wasn't exactly showcasing its novel G-Shock GB5600A -- instead, we found it hiding comfortably underneath a representative's long-sleeve shirt. Thankfully, the Casio agent was kind enough to let us give it a quick whirl. As you can likely tell by the picture above, the GB5600A is very reminiscent of those old-school watches sporting Illuminator tech, but the new revision has obviously adapted itself to the more current era. For starters, the novel G-Shock boasts Bluetooth 4.0, allowing it to pair nicely alongside iOS devices and display plenty of notifications on its itty-bitty screen -- including phone calls, text messages and emails. In addition, there's also a Time Adjustment setting for, well, automatically modifying the clock depending on where you are, as well as a Phone Finder that easily locates your iPhone, iPod or iPad with the simple touch of a button.

The sleek G-Shock GB5600A is currently only available in the Land of the Rising Sun, but the company has said it's planning to bring it to the US later this summer, priced somewhere around $200. We'll let you know as soon as we hear more concrete details; in the meantime, there's a packed gallery for your viewing pleasure right after the break.
